It is too late to ask the late Georgi Gurevich how he came up
with the idea for sub-stellar objects. In a similar situation,
Frederick Pohl was asked how he came up with the idea that a
super-massive object resides at the center of every galaxy –
a statement made by one of the characters in his novella “The
Gold at the Starbow's End” (1972). Apparently, he read it in
a popular science journal and with some speculation this
hypothesis – at the time – can be traced to works by Salpeter
and Zeldovich published at around the same time
